Hi My fishes keep on dying every week. I don't know what the correct reason is. My tank is 65 g, currently my water level is 55g.
Salt lever is 1.023, PH 8.2, nitrate 0.25. & i'm using artificial rock.

Hello, and welcome to the site.

We need lots more info to figure out exactly what's going on. Nitrates that low won't affect fish, and isn't the reason they are dying.

What do you mean by water level is 55g....your 65g tank should be filled to the plastic rim of the tank.

How long has your tank been set up?
What method did you use to kick start the first cycle?
What kind of filtration?
How many power heads?
Is the tank covered or open top?
What is the water temperature?
What type of test kit are you using?
What type of fish have you put in and lost, and how often you added them?
How did you acclimate the fish to the new tank?
What kind of artificial rock?
Do you have any live rock?
What type of substrate?

Last but not least:
What are the test results for the following......
* Ammonia
* Nitrite
* Phosphates
* Alkalinity
* calcium

Sorry the total water capacity of my tank is 65 litters and i filled 55 litters in my tank.


How long has your tank been set up?
Its almost 2.5 month ago.

What method did you use to kick start the first cycle?

Before i start the to put my fish in the tank i tested my salt , Nitrate, temperature & PH level whether everything is ok or not. When i test everything is ok. so i buy two clown fishes.

What kind of filtration?
I'm using outside filter SUN SUN HW 302.

How many power heads?
No i don't have any power heads

Is the tank covered or open top?
Its open top.

What is the water temperature?

Temperature is 80 F

What type of test kit are you using?

I'm using WILD test kit

What type of fish have you put in and lost, and how often you added them?

First i added two clown fishes and two Damsel fish

How did you acclimate the fish to the new tank?
I place the bought fish in it's cover for 20 min and then i add the tank water to that cover and finally i place the fish in to my fish tank.

What kind of artificial rock?
i don't know the exact name but it look like a dead rock

Do you have any live rock?
No i don't have a live rock

What type of substrate?
i'm using ceramic rings

Last but not least:

What are the test results for the following......
* Ammonia - I don't have a Ammonia kit
* Nitrite - 0.25
* Phosphates -8.2
* Alkalinity - I don't have
* calcium - I don't have

Ok. don't buy anymore fish till everything gets straightened out. First off, your fish are most likely dying from ammonia and nitrites because you didn't cycle your tank. Ammonia and nitrites kill fish. What you need to do is go buy live rock for your tank and put it in. I suggest getting one piece of live rock from the store and a bunch of base rock which will get seeded by the live rock. Make sure you get enough. Then fill your tank all the way up with saltwater. I would recommend making a top for your tank out of something before you get fish because some fish will jump out but that isn't important right now. The live rock will give places for bacteria to grow. The bacteria will break down the waste in the tank and turn ammonia to nitrites, and nitrites to nitrates. Next, put a piece of raw shrimp in the tank and let it rot. Test ammonia, nitrites, and nitrates everyday. You will see ammonia spike and go back to 0, nitrites spike and go back to zero, and you will see nitrates go up. Keep testing after all this has happened for a few more days and if ammonia and nitrites haven't gone up again then your tank is cycled. Do a 20 percent water change. Then add one fish every 2 weeks after this unless they are very small. If they are really small you can add 2 at a time. As I suggested earlier, You should get a top for your aquarium before you add the fish. Make one out of an egg crate or nylon screen. I have to go out the door so I don't have time to give a more in depth explanation right now.

Hi,

First...until you add ammonia, your tank will keep perfect parameters. As soon as you add a fish and it poops, which creates ammonia and that kills the fish.

You can't add any life until the tank has cycled. You have to introduce ammonia, and wait for good bacteria to build up to feed on the ammonia, and remove it from the water. The water won't even begin to cycle until you introduce ammonia, which becomes nitrites, which become nitrates and then you do water changes and remove the nitrates from the tank.

The wave is the life of the ocean, and your SW tank, so no power heads means there is no wave...and without the wave, you don't have water movement, without water movement the oxygen level in the tank is so low, the fish will die.

I have never heard of someone having phosphates at 8.2...at 1.0 I kind of panic. It would cause a huge algae bloom and at those temps you are asking for serious trouble with algae. Do you use RO (reverse osmosis) water or tap water?

Ceramic rings for substrate??? Do you know what substrate is? in a freshwater tank people use gravel, in saltwater they use nothing such as a bare bottom tank, crushed coral or sand...but ceramic rings....

I never heard of a WILD test kit. Is it a lab type, or strip?

To cycle the tank....
Toss in a chunk of raw shrimp ...or... add 1/4 cup of pure ammonia (found in any grocery store in the laundry department) ...or... pretend to feed an invisible fish flake food AKA "Ghost feeding".

First you will see the ammonia spike, then that will go to 0 and you will see nitrite spike and go back down to 0...then you will see nitrate spike, and the other two at 0. Do a 10% water change and ghost feed for one more week...AFTER 1 week test all three again and if ammonia and nitrites are still 0, THEN you do another water change and your tank has cycled, and is ready for life.

80 degrees is too warm..76 to 78 would be better.

The very best advice I can give you is your next purchase, NEEDS TO BE a good SW tank book. The Conscientious Aquarist by Robert Fenner. and/or Saltwater Aquariums for Dummies.

You should have rock built up to 1/2 the height of the tank, you can use dead rock, and just a few pieces of live rock, but ONLY rock meant for SW tanks
...the rocks from the back yard for example won't do.
